Myriad Reports ‘Invalid Port Number’ On Start-up
If you see the above error message as Myriad starts up or if the message appears while you are using
Myriad then it means that Myriad has lost communication with the SRM.
The most common cause for this message is if Myriad is configured to use MII and is started on the
computer when the SRM is not connected or is not powered up. The steps to resolve this error
message are:
a.
Check that the SRM mixer is powered up.
b.
Check that the USB cable linking the SRM to the Myriad PC is fully plugged in at both
ends.
c.
Use Device Manager (see Setting Up The MII above for more details) to ensure that
the USB Serial Converter device is listed and working correctly. If the USB Serial
Converter appears in the list with an exclamation mark beside it, it means that it is
not working. In this scenario, the best thing to do is to unplug the SRM, wait for 30
seconds and then plug it back in again. In most cases, this will resolve the situation.
d.
If all of the above appear ok, check the Com Port Number for the USB Serial Port
(see step 5 above) and make sure it is the same as the Com Port Number selected in
Myriad.
e.
If all of the above appears ok but it is still not working then you will need to contact
Using The Telephone Interface
The Telephone Interface built into the SRM allows you to plug a standard analogue telephone line
and telephone handset into the SRM and then you can route telephone calls through the SRM
mixing desk allowing you to perform telephone interviews, broadcast requests or host ‘phone in’
style shows.
What You Will Need
In order to use this facility you will need the following:
Analogue BT telephone line (standard BT domestic phone socket). Many places now have
digital or VOIP phone systems in which case you will need to talk to your telephone provider
